PPH0105 MODERN PHYSICS AND THERMODYNAMICS FET 2014/15 HEAT & THERMODYNAMICS 2/19 Upon completion of this chapter, you should be able to: 1. Show an appreciation that thermal energy is transferred from a region of higher temperature to a region of lower temperature. 2. Show an understanding that regions of equal temperature are in thermal equilibrium. 3. Convert temperatures measured in Kelvin to degrees Celsius and Fahrenheit and vice versa. 4. Show an understanding that a physical property which varies with temperature may be used for the measurement of temperature and state examples of such properties. 5. Show an understanding on the concept of absolute zero. 6. Explain the mechanism of heat conduction through solids and hence distinguish between conduction through metals and non-metals. 7. Define thermal conductivity. 8. Use the equation 𝑄 ∆𝑡 = −𝑘𝐴 𝑑𝑇 𝑑𝐿 for heat conduction. 9. Define specific heat capacity. 10. Use the equation ? = ??∆? 11. Define latent heat. 12. Use the equation ? = ?𝐿 13. Use the equation of ideal gas, 𝑝? = ??? 14. Know the relationship between Boltzmann constant and molar gas constant. 15. Use the equation 1 2 ⁄ ?𝑣 2 = 3 2 ⁄ 𝑘? 16. Use the equation for work done by gas during expansion, ? = ∫ 𝑝 ?? 17. Understand and use the first law of thermodynamics, ∆? = ∆? − ∆? 18. Understand the concept of internal energy from the first law of thermodynamics. 19. Understand the isothermal process of gas. 20. Use the equation pV = constant for isothermal changes. 21. Understand the adiabatic process of a gas. 22. Illustrate isothermal change and adiabatic change with p-V graphs and by means of the first law of thermodynamics. 23. Use the expression for work done in the thermodynamic process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
